I Have a couple bad bulbs Or bad connections on the inside flush mounted lights. Is there a way to get at the bulb? It feels like the globes are tight and I can't figure out how to get at the bulb. Does anyone have any ideas? Thanks in advance

With the '15 that may or may not be the case, I think that's about when they changed over, but my '13 has twist off covers with replaceable bulbs. If I recall the cover will twist off of both styles, but the later ones are all LEDs that are not replaceable except by replacing the entire fixture.
